The illegitimate referendum saw Iraqis in KRG-controlled areas and in a handful of territories disputed between Erbil and Baghdad, including ethnically mixed Kirkuk and Mosul vote on whether or not to declare independence.

In recent days, Ankara has launched a military exercise across the border from KRG territory and threatened restrictions at the main frontier crossing.

Along with Iraq 's central government, Turkey , the U.S., Iran, and the UN have spoken out against Monday's illegitimate poll, warning it would distract from the ongoing fight against Daesh and further destabilize the region.
